信报处理系统访问单元的研究及公共传真访问单元的实现

THE RESEARCH ON ACESS UNITS IN MESSAGE HANDLING SYSTEM AND THE IMPLEMENTATION OF PUBLIC TELEFAX ACCESS UNITS

访问单元（ＡＵ）是信报处理系统（ＭＨＳ）的重要功能对象，信报处理系统通过它可以与传统的通信系统集成。本文将讨论ＭＨＳＡＵ的概念、类型、功能、作用和配置，着重分析公共传真访问单元（ＰＦＡＸＡＵ）应具有的基本功能。文章的最后介绍了一个ＰＦＡＸＡＵ系统高效、实用的实现方法。

Access Unit(AU) is an important functional object in Message Handling System (MHS). Various traditional communication systems can be integrated into MHSwith it. In this paper, we discuss AU's concept, types, functions, effects and configurations while focusing on analysing the fundamental functions of Public Telefax AU(PFAXAU). Finally, the efficient and practical implementation of a PFAXAU systemis introduced.
